In this embodiment, the one or more supporting assemblies 2 are twosupporting assemblies 2 respectively connected to two ends of thesupporting board 1 along the length direction of the supporting board 1.Two of the supporting foot frames 21 rotate to define a storage state inwhich the two of the supporting foot frames 21 abut the supporting board1 and a use state in which the two of the supporting foot frames 21 areunfolded relative to each other. When the foldable stool 100 is in theuse state, two of the second ends 2212 of two of the connecting members221 of two of the connecting assemblies 22 slide to be connected to twoof the fastening assemblies 222. When the foldable stool 100 is in thestorage state, the two of the second ends 2212 of the two of theconnecting members 221 of the two of the connecting assemblies 22 slidein the one or more extended sliding grooves 11 to approach each other.

The supporting foot frame 21 comprises two supporting rods 211 spacedapart from each other along a width direction of the supporting board 1.One end of each of the two supporting rods 211 is pivotally connected tothe supporting board 1, and the supporting foot frame 21 furthercomprises a plurality of reinforce rods 212 extending and connectedbetween the two supporting rods 211. In some embodiments, the foldablestool 100 may comprise a single of the supporting assemblies 2 as longas the supporting assembly 2 can support the supporting board 1. In thisembodiment, the two of the supporting foot frames 21 of the twosupporting assemblies 2 are unfolded relative to each other and are eachangled with respect to the lower side of the supporting board 1 todefine an obtuse angle, and the connecting member 221 is connected tothe supporting foot frame 21 and the lower side of the supporting board1. In this embodiment, when the foldable stool 100 is in the use state,a user can directly sit on an upper side of the supporting board 1, orthe foldable stool 100 can be used as a stepladder.

The fastening assembly 222 comprises a pivotal body 2221 pivotallyconnected to the supporting board 1, and the pivotal body 2221 ispivotally connected to the lower side of the supporting board 1. A firstend 2222 of the pivotal body 2221 comprises a fastening groove 2224having an opening facing the supporting board 1, and the fasteninggroove 2224 is located on a side of the pivotal body 2221 away from thesupporting foot frame 21.

The first end 2222 of the pivotal body 2221 comprises a guiding slope2225. A first end of the guiding slope 2225 is connected to the openingof the fastening groove 2224, and a second end of the guiding slope 2225obliquely extends away from the supporting board 1. The second end 2212of the connecting member 221 is configured to slide to abut the guidingslope 2225 to make the pivotal body 2221 pivot. When the second end 2212of the connecting member 221 corresponds to the fastening groove 2224,the pivotal body 2221 pivots and drives the fastening groove 2224 tomove toward the supporting board 1 so as to enable the second end 2212of the connecting member 221 to be fastened to the fastening groove2224. When the foldable stool 100 is changed from the storage state tothe use state, the supporting foot frame 21 pivots toward the supportingboard 1 until the second end 2212 of the connecting member 221 abuts theguiding slope 2225. When the supporting foot frame 21 continuespivoting, the second end 2212 of the connecting member 221 slides on theguiding slope 2225 to make the first end 2222 of the pivotal body 2221pivot until the second end 2212 of the connecting member 221 moves intothe fastening groove 2224. At this time, rotation of the supporting footframe 21 is inhibited.

The fastening assembly 222 further comprises a resetting member 2226disposed between the supporting board 1 and a second end 2223 of thepivotal body 2221. When the second end 2223 of the pivotal body 2221 ispressed to approach the supporting board 1 so as to make the first end2222 of the pivotal body 2221 move away from the supporting board 1, theresetting member 2226 is compressed to store an elastic force. In thisembodiment, the resetting member 2226 is a spring. During an unfoldingprocess in which the foldable stool 100 is changed from the storagestate to the use state, the resetting member 2226 ensures that theguiding slope 2225 always abuts the second end 2212 of the connectingmember 221. During a folding process in which the foldable stool 100 ischanged from the use state to the storage state, the second end 2223 ofthe pivotal body 2221 is pressed by the user to make the first end 2222of the pivotal body 2221 move away from the supporting board 1. At thistime, the second end 2212 of the connecting member 221 can leave thefastening groove 2224, and the supporting foot frame 21 can pivot andabut the lower side of the supporting board 1.

When the fastening groove 2224 movestoward the supporting board 1 to be fastened to the sliding rod 2213,the two ends of the sliding rod 2213 abut the one or more blockingmembers 111. In this embodiment, the one or more blocking members 111are two blocking members 111 due to the two supporting assemblies 2being provided, and the two blocking members 111 are located on two endsof the one or more extended sliding grooves 11 along the lengthdirection of the supporting board 1. The one or more blocking members111 cooperate with the fastening assembly 222 to inhibit the sliding rod2213 from sliding.

Referring to the figures, during the unfolding process, the upper sideof the supporting board 1 abuts the ground, a first one of thesupporting foot frames 21 abutting the lower side of the supportingboard 1 is pulled by the user, and the first one of the supporting footframes 21 pivots and drives the sliding rod 2213 to slide in the slidinggroove 11 until the sliding rod 2213 abuts the guiding slope 2225. Thefirst one of the supporting foot frames 21 continues to be pulled, thesliding rod 2213 slides on the guiding slope 2225, and the first end2222 of the pivotal body 2221 swings and drives the opening of thefastening groove 2224 to move away from the supporting board 1 until thesliding rod 2213 is inserted into the fastening groove 2224. At thistime, the two ends of the sliding rod 2213 abut a first one of the twoblocking members 111. The unfolding process of a second one of thesupporting foot frames 21 is the same as the unfolding process of thefirst one of the supporting foot frames 21, and will not be describedbelow. When in the use state, the supporting board 1 is turned over, andeach of the supporting foot frames 21 is angled with respect to thesupporting board 1 to define the obtuse angle. At this time, the usercan directly sit or stand on the foldable stool 100.

During the folding process, the upper side of the supporting board 1abuts the ground, the second end 2223 of the pivotal body 2221 is pushedby the user, and the opening of the fastening groove 2224 moves awayfrom the supporting board 1. The first one of the supporting foot frames21 is pulled by the user to drive the sliding rod 2213 to slide awayfrom the fastening groove 2224 until the first one of the supportingfoot frames 21 abuts the supporting board 1. The second one of thesupporting foot frames 21 is pulled by the user in the same way, and thetwo of the supporting foot frames 21 pivot and approach each other.
